Set parallel to baffle 222, two rollers 232 of 23 the same side of cushion block are embedded in guide rail 233 and slide so that reduce cushion block 23 it
Between frictional force, facilitate operating personnel drag cushion block 23.In addition, as shown in figure 3, in cushion block 23 close to the side wall of 31 side of limiting plate
On be fixed with draw ring 231, facilitate operating personnel to catch draw ring 231 to move and carry to drag cushion block 23.
As shown in Fig. 2, in the present embodiment, spirit level 21 is horizontally fixed with 2 side wall of supporting block, according in spirit level 21
Bubble position determines whether supporting block 2 is smooth with ground, if bubble deviates, operating personnel are according to offset direction to ground
Handled, untill supporting block 2 is adjusted to horizontal level.In addition, in order to determine the supporting block 2 of symmetrical both sides in same water
In plane, as shown in Figure 3 and Figure 4, winder 24 is fixed on the outer wall of side U-shaped block 22, volume has drawstring on winder 24
241, level indicates graduation mark on the outer wall of 22 homonymy of opposite side U-shaped block, the distances of adjacent two graduation marks and cushion block 23
Consistency of thickness.Outer wall position where drawstring 241 is pulled to graduation mark, and drawstring 241 is kept horizontal level, with 241 He of drawstring
Spacing between graduation mark determines the difference in height between both sides U-shaped block 22, and adjusting the cushion block 23 on U-shaped block 22 according to difference in height counts
Amount repairs ground, ensures that the cushion block 23 on both sides top is located in same level.
The secondary beam 4 lifted in order to prevent is subject to the influence of subsequent parts lifting and deviates initial position, as shown in figure 3,
Perforation is provided with screw hole 41 on 4 both ends of secondary beam and cushion block 23, using the bolt 42 being screwed in screw hole 41 that secondary beam 4 and cushion block 23 is tight
Gu live.
In addition, the lifting of supporting block 2 for convenience, as shown in figure 3, being fixed respectively on the symmetrical both sides side wall of U-shaped block 22
There is hanging ring 43.
The course of work：Operating personnel are determined after test pile 1, and foundation pile 1 is nearby handled on ground, treats floor treatment
After supporting block 2 is lifted into 1 both sides of foundation pile.Determine whether ground is smooth according to spirit level 21, pull the alignment of drawstring 241 to carve
Line is spent, determines supported on both sides piece 2 whether in same level；If supporting block 2 turns turning handle 314, opens limit there are height difference
Position plate 31, is adjusted the cushion block 23 in U-shaped block 22, after adjustment, shuts limiting plate 31, tighten securing rod 312.Treat thousand
After jin top 11 and girder 12 install, secondary beam 4 is lifted on girder 12 one by one, and the bolt 42 at 4 both ends of secondary beam is screwed into
In the screw hole 41 of cushion block 23, and after the secondary beam 4 fixed hangs oneself and loads onto clump weight 13, you can start to test.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
